It's not exactly a 'Netflix-Original'. Started out as a joint production between Universal and Legendary Films with a budget of 70-million. After completion, Universal wasn't happy with it, Legendary didn't like their feedback and they had a falling out -- the planned 2016 summer theatrical release was canceled. Chinese-owned Legendary Films shopped around, Netflix picked it up as an already finished movie and branded it a 'Netflix-Original'.

Not awful. Competent, experienced cast; OK story and decent effects contribute to a production that had some budget to work with. A few plot-holes here and there, like beings that can fly over things, yet laying iron shavings on the ground provides a barrier of protection because they can't step in it. Contrived ending, and, so what if they kinda-sorta borrowed a central plot mechanism from the 1995 anime movie "Ghost in the Shell" https://trakt.tv/movies/ghost-in-the-shell-1995 -- it's an enjoyable watch... :-)
